Neighbor is relative here :), they live about two miles away. It's a German tradition in the countryside to do that when the farmers wives bake those big loaves of bread in the "Backhaus", a little outside house with a large stone oven. I guess they make the cake after the bread is done, while the stones are still hot. My wife gets it from a friend from time to time. This shit is out there. Can't compare it to any industrially produced bread.
